Calculate the LCM of 977,651,909,217

Given numbers are 977,651,909,217

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 977,651,909,217 is 192716181.

Find LCM of 977,651,909,217 with Prime Factorization


3 977, 651, 909, 217
7 977, 217, 303, 217
31 977, 31, 303, 31
977, 1, 303, 1

Multiply the prime numbers at the bottom and the left side.

3 x 7 x 31 x 977 x 1 x 303 x 1 = 192716181

Therefore, the lowest common multiple of 977,651,909,217 is 192716181.

LCM Formula to Find Lowest Common Multiple of 977,651,909,217

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

977 x 651 x 909 x 217 = 125458233831

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

977 : 1, 977

651 : 1, 3, 7, 21, 31, 93, 217, 651

909 : 1, 3, 9, 101, 303, 909

217 : 1, 7, 31, 217

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 977,651,909,217, is 1.

Now, the common factors can be found like this.

977:977

651:3x 7x 31

909:3x 3x 101

217:7x 31

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 7x 31 = 651

Therefore, the value for common factors is 651.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 125458233831/(1x651)

LCM = 125458233831/651

LCM = 192716181

Thus, we can understand that the LCM of 977,651,909,217 is 192716181.
